Part Number: TPS65140-Q1 Other Parts Discussed in Thread: PMP9780 , TPS65131 Dear team,
Could you please help recommend one appropriate device to support below LCD specs? VIN=VDD=3.3V, there are four output voltages as below.
Thanks & Best Regards,…
Part Number: TPS65140-Q1 Other Parts Discussed in Thread: TPS65140 , TPS65141 Hi, I am Hwadong Song of TOVIS
As I wroted in title, our tps65140 power circuit doesn't work well.
Specifically, the output is too low(0V or 7V). So could you check wheth…
Part Number: TPS65140 Hi, I am Hwadong Song of TOVIS co. ltd. in Korea.
I am trying to apply tps65140 IC in our LCD module driving Board.
But in our circuit as attached file, the V03 voltage is not correct.
(Specifically, V03 is 0V, and other V01 & V02…
Part Number: TPS65140 Hey there,
i was going through the design steps for the TPS65140 and stumbled over the first equation. Are you shure the equation and the result is right? I typed it into my calcuator and get 1.288....and not 0.73 as in the Datasheet…
Part Number: TPS65140 Dear all，
Attached is the schematic diagram. On page 5, it is the circuit diagram of TPS65140. The following is the screenshot.Arrow P5V is 5V power input, output VOFFSET, VRST, VBAIS and P3P3V_TPS. The power chip enable pin is powered…
Part Number: TPS65140 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models Hi Team,
My customer would like to confirm the loop stability on TPS65140, do you have any simulated tool (TINA or …) can share with us?
Devices that are functionally similar to TPS65100 are TPS65101/105 and TPS65140. For other devices on your list, I will assign this thread to appropriate product line within TI and one of the engineers will respond to you directly.

I am working to replace MAX1531ET by TPS65140PWPR in a Infotaiment system.
This will drive a 7” TFT bipolar display , that requires the following voltages:

HI team member
When EN is disabled, VOI1 of TPS65140 ouputs nearly VIN by boost DC/DC configuration (VIN -> Inductance -> diode -> VO1).
This means LCD panel 's AVDD is applied VIN(5V) vorlage during EN is diabled,
I find an voltage drop on VO1 when the ambient temperature is down to -40 degree.(only VO1 rail)
I have modified compensation component, Cin, and Cout. Also check the component working temperature.
But this issue still happened.
Did you have…
